System configurations
Circulation pump PC1 is controlled by the control unit in the heat pump
module.
If a fresh water station is installed, it must have its own control unit.
If a buffer cylinder is used, a 3-way valve VC0 must be installed in
accordance with the system solution. The 3-way valve replaces the T-
unit in the safety assembly (
Chapter 5.1.1) and is connected
electrically to terminal VC0 on the installer module.

Non-return valve
One non-return valve in each heating circuit is required for preventing
natural circulation in the heating system in summer mode. Natural
circulation may arise as the domestic hot water 3-way valve is open to
the heating system when the heat pump prepares DHW heating.
The heat pump and heat pump module may be installed
only in accordance with the official system solutions
provided by the manufacturer.
Other system solutions are not allowed. Any damage and
problems resulting from prohibited installation are
excluded from liability.
